Definitions

  • the present invention relates to a device for locking a tubing hanger to a tubing spool or the like in a subsea completion system. More particularly, the invention relates to such a device which is operable independently of both the tubing hanger and the tubing hanger running tool.
  • a typical prior art completion system for subsea oil and gas wells comprises a subsea wellhead which is installed at the upper end of a well bore, a production . member which is connected to the top of the wellhead, and a tubing hanger which is landed in the production member and which supports a production tubing string that extends through the well bore and into the well.
  • the subsea completion system is often connected to a surface vessel through a low pressure riser which in turn is connected to a subsea blowout preventor ("BOP") that is secured to the top of the production member.
  • BOP subsea blowout preventor
  • the tubing hanger is normally installed in the production member using a tubing hanger running tool ("THRT").
  • THRT tubing hanger running tool
  • a lockdown mechanism is usually actuated to secure the tubing hanger to the production member.
  • a typical lockdown mechanism includes a lock ring which is supported on the tubing hanger and is expandable into locking engagement with a corresponding groove that is formed in the production member.
  • THRT a release mechanism on the THRT is actuated to release the tubing hanger from the THRT.
  • prior art THRT's must usually include a lockdown tool for actuating the lockdown mechanism on the tubing hanger and a release tool for actuating the release mechanism on the THRT.
  • these tools are often operated by hydraulic pressure which is supplied to the THRT through a hydraulic umbilical that is connected to the surface vessel.
  • SSTT subsea test tree
  • shear joint also be used.
  • the SSTT is connected to the top of the THRT
  • the shear joint is connected to the top of the SSTT
  • the entire assembly is lowered on a running string through the low pressure riser and the BOP.
  • the hydraulic umbilical for the THRT is run along side the running string and then routed to the THRT through the shear joint and the SSTT.
  • the SSTT and the shear joint allow for a controlled shut-in of the well in the event of a blowout or other emergency.
  • the valves in the SSTT are closed, the lower BOP pipe rams are sealed around the SSTT and, if necessary, the upper BOP shear rams are actuated to sever the shear joint and thereby separate the running string from the SSTT.
  • the lower portion of the severed shear joint can be retrieved and a replacement shear joint then re-connected to the SSTT.
  • the SSTT and the shear joint allow for hydraulic control of the THRT to be easily re-established. Once the replacement shear joint is connected to the SSTT, the hydraulic umbilical is again connected with the THRT.
  • a lockdown device for securing a tubing hanger to a production member.
  • the lockdown device comprises a lockdown member which is mounted on the production member and is movable into and out of engagement with a corresponding locking profile on the tubing hanger.
  • the lockdown device further comprises an actuating mechanism for moving the lockdown member into and out of engagement with the locking profile.
  • the lockdown member is disposed at least partially in a lockdown port which extends through the production member to the central bore.
  • the lockdown member comprises a stem portion which is disposed in the lockdown port and a base portion which is engaged by the actuating mechanism.
  • the actuating mechanism comprises an actuator shaft which includes a first end that engages the lockdown member and a second end that is adapted to be engaged by a tool.
  • the actuator shaft is rotatably supported relative to the production member, and the first end of the actuator shaft is coupled to the lockdown member through a threaded connection.
  • the tubing hanger lockdown device of the present invention does not require the use of a hydraulic umbilical.
  • the lockdown device since the lockdown device is operable independently of the THRT, the THRT does not require a hydraulic umbilical. Consequently, no need exists for an SSTT during installation of the tubing hanger or workover of the well.
  • the hydraulic umbilical and SSTT can be dispensed with, the production member can be easily and economically connected to a surface vessel using a surface BOP and high pressure riser.

  • Figure 3B is a schematic representation of the surface portion of the completion system shown in Figure 1.
  • a subsea completion system in accordance with the present invention is shown to comprise a number of novel tubing hanger lockdown devices, generally 10.
  • the production member 14 is depicted as a horizontal Christmas tree, the lockdown devices 10 could be used in conjunction with any component which is adapted to support a tubing hanger, such as a conventional Christmas tree, a wellhead, a tubing spool, a spool tree or an adapter. Therefore, the term production member should be interpreted to include all such components.
  • the production member 14 includes a body 18, a central bore 20 which extends axially through the body, a production outlet 22 which extends laterally through the body from the production bore, and a tubing hanger landing shoulder 24 which is formed in the central bore.
  • the production member 14 ideally also includes an orientation helix 26 which is formed in either the central bore 20 or on an orientation sleeve which is attached to the central bore.
  • the tubing hanger 12 is supported in the central bore 20 on the landing shoulder 24.
  • the tubing hanger 12 includes a generally cylindrical body 28, a production flowpath 30 which extends axially through the body, and a production port 32 which extends generally laterally between the production flowpath and the production outlet 22.
  • the production flowpath 30 may be sealed above the production port 32 by one or more wireline plugs 34, 36.
  • the tubing hanger 12 is installed in the production member 14 using a THRT
  • each lockdown device 10 comprises a lockdown member 44 which is adapted to engage a corresponding locking profile 46 that is formed on the outer diameter of the tubing hanger 12 (as shown best in Figure 1 ), and an actuating mechanism 48 which functions to move the locking member into and out of engagement with the locking profile.
  • the lockdown member 44 can comprise any appropriate pin, screw, dog, segment, collet, ring or the like.
  • the actuating mechanism 48 can comprise any suitable screw, cam, toggle, shaft or the like which is translated or rotated by a corresponding electric, hydraulic or manual linear or rotary actuator.

  • the lockdown member 44 comprises a locking segment which includes a base portion 50 that is attached to or formed integrally with a stem portion 52.
  • the base portion 50 is slidably supported in a bonnet 54 which is attached to the production member 14 by suitable means, such as a number of stud and nut assemblies 56.
  • the stem portion 52 is disposed in a corresponding lockdown port 58 which extends generally laterally through the production member 14 to the central bore 20.
  • the stem portion 52 includes a distal end which comprises a lockdown profile 60 that is adapted to engage the locking profile 46 on the tubing hanger 12.
  • the stem portion 52 is ideally sealed to the lockdown port 58 by a suitable sealing assembly, such as a packing 62 which is held in place by a gland nut 64.
  • the actuating mechanism 48 is shown to comprise an actuator shaft 66 which includes a first end 68 that engages the lockdown member 44 and a second end 70 that is adapted to be engaged by a suitable tool, such as a rotary tool on an ROV (not shown).
  • the actuator shaft 66 is rotatably supported on the bonnet 54 through a suitable bearing assembly 72 which is disposed in a housing 74 that in turn is connected to the bonnet with, for example, threads 76 and one or more set screws 78.
  • the lockdown device 10 may also include an ROV bucket 82 to help guide an ROV rotary tool into engagement with the actuator shaft 66.
  • the actuator shaft 66 and the housing 74 may be extended to any length to enable the ROV to easily access the ROV bucket 82.
  • the actuator shaft 66 and housing 74 of the right-hand lockdown device 10 have been extended to clear the wing valve block 84.
  • the actuator shaft 66 may be rotated by a diver or by any suitable rotary motor.
  • the actuator shaft 66 is rotated to cause the lockdown member 44 to move radially inward or outward relative to the production member 14. This in turn forces the lockdown profile 60 on the stem portion 52 into or out of engagement with the locking profile 46 on the tubing hanger 12.
  • the bearing assembly 72 ideally comprises a thrust bearing to transfer the axial reaction loads from the lockdown member 44 and the actuator shaft 66 through the housing 74 and the bonnet 54 and ultimately to the production member 14.
  • the lockdown devices 10 may be actuated to secure the tubing hanger in the central bore 20.
  • the tubing hanger will be prevented from moving upwards in the face of vertical forces which are caused by, for example, pressure in the well bore below the tubing hanger or thermal expansion of the production tubing string which is suspended from the tubing hanger.
  • the THRT 38 can be released from the tubing hanger by simply rotating the running string until the threads 42 are disengaged.
  • the tubing hanger lockdown device 10 offers many advantages over prior art lockdown mechanisms.
  • the lockdown device 10 Since the lockdown device 10 operates independently of the THRT 38, no need exists to supply the THRT with hydraulic pressure. Consequently, the usual hydraulic umbilical which supplies conventional THRT's with hydraulic pressure can be eliminated. In addition, since the THRT 38 does not need a hydraulic umbilical, an SSTT is not required during installation of the tubing hanger 12 or workover of the well. Referring to Figures 3A and 3B, the locking device 10 also facilitates the connection of the subsea completion system to a surface vessel 86 using a surface BOP 88 and a small diameter, relatively light weight high pressure riser 90.
  • the production member 14 is connected to a wellhead 92 which is installed at the upper end of a well bore (not shown), and the tubing hanger 12 is landed in the production member using a THRT 38 which is connected to a running string 94.
  • the top of the BOP 88 is ideally connected to a telescopic joint 96 which is attached to a diverter 98 that is supported on the surface vessel 86, and the bottom of the BOP is connected to the top of the riser 90 just above a riser tensioner 100.
  • an optional subsea isolation device 102 comprising shear rams 104 may be positioned between the production member 14 and the riser 90 if desired or required.
